I had a chance to get into the PiDP-1 software today. It's pretty cool. There's a lot there to get your head around because Obsolescence Guaranteed is basically recreating the whole PDP-1 ecosystem from the early sixties running on a Raspberry Pi 5. As part of that effort they are recovering the "paper tape" images for numerous demos created for the PDP-1 at the dawn if the computer era.

So I fired up a virtual PDP-1 Console (which will be replaced with the physical PiDP-1 down the road), loaded up a virtual tape drive with a recovered "snowflake" demo tape image, and "hit" the virtual READ IN switch on the console. After a little virtual  "blinken light" action the output appeared "full screen" on my Type 30 reproduction.  Here is what it looks like.

If you look closely you can see the faint outline of the 4:3 LCD screen. I think if I use a darker gel filter I can eliminate that or at least mitigate it further.
